OK, a supplementary question that someone might be able to help with specifically for my Garmin etrex 10.
I do geocaching from home, and make occasional forays down to Dartmoor. The etrex 10 supports a maximum of 1,000 waypoints. So lets say I do a pocket query of 1,000 caches for home, and another one of 1,000 caches for Dartmoor. I obviously can't have both sets loaded on the etrex at once, but can I delete one set and upload the other as I need them? Will the etrex maintain a record of which caches I've found overall? Or will it just get hopelessly confused?
Thanks in advance.
Stuart.
